Item Metadata only Block practice encourages motor learning of dynamic balance skill in healthy young adults(2018) Aladro Gonzalvo, Arian Ramon; Aladro Gonzalvo, Arian RamonIntroduction: The scheme of learning complex skills duringpractice affects motor performance [1, 3], however, not much isknown about the most efficient way to learn fundamental untrainedmotor skills. Locomotor skills such as walking, running, sitting andgetting up, involve temporarily optimal and precise dynamic move-ments of body weight displacement in frontal and sagittal planes[2, 4]. Purpose of this study was to determine if practice schememodifies motor learning of a dynamic balance skill in healthy youngsubjects. Methods: After sample power analysis, 63 universitystudents (20.63 62.58 years) without balance disorders andprevious training, participated in the study. They were randomlyassigned to 1 of 3 practice schedules (block “B,” random “R” orincreasing “I”). Learning task was to move body weight laterally ona platform of force according to visual feedback provided ona computer. Eighteen trials were carried out during acquisition,and again 24 hours later, during evaluation of retention of the skill.Force-load was manipulated between trials ranging from 35 to15% of body weight, in order to get contextual interference effect[6]. Outcome measures were execution errors and time of execu-tion (s) during acquisition and retention of the skill. Experimentalstudy, in accordance with Declaration of Helsinki, was approvedby Institutional Review Board (Universidad de las Ame´ricas, Ecua-dor), and participants gave informed consent.Item Metadata only Drenaje linfático manual versus masaje convencional en el tratamiento de pacientes con mastitis puerperal noinfecciosa(2018) Aladro Gonzalvo, Arian Ramon; Aladro Gonzalvo, Arian RamonLa mastitis puerperal no infecciosa es una inflamación de las glándulas mamarias que causa dolor, calor y enrojecimiento. Generalmente, el tratamiento conservador incluye la aplicación del masaje convencional (MC). Sin embargo, hay escasa evidencia que analice el efecto del drenaje linfático manual (DLM), siendo su aplicación eficaz en la remoción de líquidos. El objetivo de este estudio fue comparar el efecto del DLM vs MC. El estudio fue un ensayo clínico aleatorizado que incluyó 15 madres primigestas repartidas en un grupo control (GC) y dos grupos experimentales GDLM y GMC de 5 participantes cada uno. En todos los grupos se evalúo la cantidad de leche extraída, los perímetros mamarios (longitudinales y transversales) y el dolor, antes y después de 6 sesiones de intervención. Se realizaron pruebas no paramétricas para comparar las diferencias entre los grupos. A partir de la sesión 3 de tratamiento se observó una diferencia significativa en la cantidad de leche extraída y de los perímetros mamarios, cuando comparamos el GDLM con el GMC (p<0,05). En contraste, el dolor fue menor en el GMC comparado con el GDLM y el GC (p<0,05). El GC presentó niveles superiores del dolor y menor cantidad de leche en comparación con los grupos experimentales (p<0,05). Estos resultados sugieren que el tratamiento ideal consistiría en combinar el MC con el DLM. Además, la aplicación de estas técnicas manuales no invasivas pueden ser beneficiosas en el puerperio, debido a que evitan el consumo de medicamentos cuyos efectos pueden ser transmitidos al bebé.Item Metadata only Effects of local ischemic compression on upper limb latent myofascial trigger points: a study of subjective pain and linear motor performance(2019-03-04) Aladro Gonzalvo, Arian Ramon; Aladro Gonzalvo, Arian RamonObjective. To analyse the effect of the manual ischemic compression (IC) on the upper limb motor performance (MP) in patients with LTrPs. Materials and Methods. A quasiexperimental study was performed in twenty subjects allocated to either patients group with LTrPs (PG, n=10) or healthy group with no symptoms (HG, n=10). Subjective pain and linear MP (movement time and Fitts’ Law) were assessed before and after a linear tapping task. Data were analysed with mixed factorial ANOVA for intergroup linear motor performance differences and dependent t-student test for intragroup pain differences. Results. PG had a linear MP lower than the HG before treatment (p < 0.05). After IC, the PG showed a significant decrease of pain (4.07 ± 1.91 p < 0.001). Furthermore, the movement time (15.70 ± 2.05 p < 0.001) and the Fitts’ Law coefficient (0.80 ± 0.53 p < 0.001) were significantly reduced. However, one IC session did not allow the PG to get the same MP than the HG (p < 0.05). Conclusion. The results suggest the IC effectiveness on pain and MP impairment in subjects with LTrPs. However, the MP of these patients is only partially improved after the IC application.Item Metadata only Exercise protects cardiovascular recovery from stress in a sample of black ethnicity adolescents(2018) Aladro Gonzalvo, Arian Ramon; Aladro Gonzalvo, Arian RamonBACKGROUND: Exaggerated cardiovascular response to a subsequent psychosocial challenge (cardiovascular reactivity) have an adverse effect on future cardiovascular risk status in younger populations. Several studies have shown that black individuals exhibited significantly greater blood pressure (BP) and heart rate (HR) responses to stressors than white individuals. The purpose of the study was to determine whether interval exercise reduces cardiovascular reactivity and recovery from stress in black adolescents. METHODS: In a counterbalanced order and one-week apart, black Cuban adolescents (n=25) completed an interval exercise program followed by the Trier Social Stress Test for Child (TSST-C) and no exercise followed by the TSST-C. The exercise consisted of a cycle ergometer fitness test (5-min, 50 rpm, 60% HR reserve), followed by 60-s rest, and another bout of exercise (6-min, 80 rpm, 30-s intervals) at the resistance that elicited the target HR reserve during the fitness test. Adolescents rested 2-min before completing another 6- and 4-min interval exercises. Following a 5-min post-intervention period, adolescents completed the TSST-C. BP, HR and heart rate variability (HRV) were measured before, during and after the exercise and TSST-C. RESULTS: Systolic blood pressure (SBP) remained unchanged following exercise. TSST-C-induced changes in BP, HR and HRV reactivity were not reduced for aerobic exercise. Recovery SBP and HR were reduced in the exercise condition (P<0.01, CI95% = -8.36, -2.51, and P<0.01, CI95% = -8.07, -4.31, respectively). CONCLUSIONS: Acute interval aerobic exercise appears to have a significant impact on cardiovascular recovery in black adolescents who have suffered stressful events.Item Metadata only Impact of work and recreational physical activity on prediabetes condition among U.S. Adults: NHANES 2015–2016(2021-02) Aladro Gonzalvo, Arian Ramon; Aladro Gonzalvo, Arian RamonMore minutes of physical activity (PA) accumulated during a day are associated with a lower risk of diabetes mellitus type 2. However, it is less known if distinct dimensions of PA can produce a different protective effect in the prevention of prediabetes. The aim of this study was to analyze the impact of work and recreational PA on prediabetes among U.S. adults during the period 2015–2016 using the National Health and Nutrition Examination Survey (NHANES) database. Individuals (n = 4481) with hemoglobin A1c (HbA1c) test values of 5.7% to 6.4% were included. A logistic regression multivariate-adjusted analysis was conducted to estimate the association between the odds ratios (ORs) and 95% confidence intervals (CIs) of prediabetes, with work and recreational PA. The prevalence of prediabetes among U.S. adults was lower in physically active individuals both at work (~24%) and recreational (~21%) physical activities compared to individuals who were not physically active (27 to 30%). Individuals lacking practice of recreational PA had a high risk of prediabetes (OR = 1.26, 95% CI: 1.080 to 1.466). PA may be a protective factor for prediabetes conditions depending on gender, age, ethnic group, waist circumference, and thyroid disease.Item Metadata only On the use of natural user interfaces in physical rehabilitation: a web-based application for patients with hip prosthesis(2018) Aladro Gonzalvo, Arian Ramon; Aladro Gonzalvo, Arian RamonThis study aims to develop a telemedicine platform for self-motor rehabilitation and remote monitoring by health professionals, in order to enhance recovery in patients after hip replacement. The implementation of such a technology is justified by medical (improvement of the recovery process by the possibility to perform rehabilitation exercises more frequently), economic (reduction of the number of medical appointments and the time patients spend at the hospital), mobility (diminution of the transportation to and from the hospital) and ethics (healthcare democratization and increased empowerment of the patient) purposes. The Kinect camera is used as a Natural User Interface to capture the physical exercises performed at home by the patients. The quality of the movement is evaluated in real-time by an assessment module implemented according to a Hidden-Markov Model approach. The results show a high accuracy in the evaluation of the movements (92% of correct classification). Finally, the usability of the platform is tested through the System Usability Scale (SUS). The overall SUS score is 81 out of 100, which suggests a good usability of the Web application. Further work will focus on the development of additional functionalities and an evaluation of the impact of the platform on the recovery process.Item Metadata only Telerehabilitation platform for hip surgery recovery(2017-10-16) Aladro Gonzalvo, Arian Ramon; Rybarczyk, Y., Kleine Deters, J., Cointe, C., Aladro Gonzalo, A. y Esparza, D.The enhancement of ubiquitous and pervasive computing brings new perspectives in terms of medical rehabilitations. In that sense, the present study proposes a Web-based platform to promote the reeducation of patients after hip replacement surgery. This project focuses on two fundamental aspects in the development of a suitable telerehabilitation application, which are: (i) being based on an affordable technology and (ii) providing the patients with a real-time assessment of the correctness of their movements. A comparative test shows that the movement's evaluation carried out by therapists is consistent with the output of the automatic assessment module. Improvements of the algorithm are discussed, in order to increase the accuracy and depth of the analysis.
